Large-cage occupation and quantum dynamics of hydrogen molecules in sII clathrate hydrates

Richard Gaal, Livia Eleonora Bove Kado, Umbertoluca Ranieri

Hydrogen clathrate hydrates are ice-like crystalline substances in which hydrogen molecules are trapped inside polyhedral cages formed by the water molecules. Small cages can host only a single H-2 molecule, while each large cage can be occupied by up to f ...

Solvent- and catalyst-free reduction of CO2 with ammonia borane

Andreas Züttel, Youngdon Ko, Liping Zhong

Ammonia borane (AB) has been extensively studied as a solid-state hydrogen storage material. On the other hand, its reactivity with CO2 is still unclear, especially in the solid state. By carefully controlling the CO2 pressure and temperature, AB efficient ...

Influence of temperature on phase assemblages of belite-ye'elimite cement

Karen Scrivener, Barbara Lothenbach, Diana Londoño Zuluaga, Natechanok Chitvoranund

This paper studies the effect of temperature on the phase assemblages of belite-ye'elimite cement. A comparison is made between thermodynamic modelling and experimental data at 28 and 180 days of hydration at 5, 20, 40, and 60 degrees C. The fast reaction ...

Homogeneous catalysis with nitrous oxide

Kay Severin

Nitrous oxide (N2O; ‘laughing gas’) is a powerful oxidant, but chemical transformations are hampered by the inert character of this gas. Recent advances in using N2O as an oxidant in metal-catalyzed reactions are discussed. The focus will be on reactions t ...
